A rotary wire brush, such as a wheel brush, e.g., double-stringer or dually brush, cup brush, bevel brush, or knotted end brush, composed of knotted brush wire tufts of multistrand construction each having at least a plurality of brush wire strands, preferably at least a plurality of pairs of, i.e., at least three, strands each formed of at least a plurality, preferably at least a plurality of pairs of, i.e., at least three, wires. The wires forming strands are twisted, braided, or twisted and braided, and the strands that form tufts are twisted, braided, or twisted and braided. A preferred brush employs a center disc, e.g., hub, with radially offset tuft anchor holes, which can have different sizes, from which twist knot tufts, which also can have different sizes, can outwardly extend from the disc different distances by being configured with an offset trim preferably having different trim lengths

A double-stringer rotary brush assembly formed of a pair of brush wire mounting hubs having sets of alternating radially staggered radially innermost and outermost brush wire tuft mounting holes having different hole sizes with brush wire tufts extending radially outwardly therefrom having at least one of (a) different lengths, (b) an offset trim, and/or (c) differently sized knots anchoring the tufts thereto. One hub can be angularly offset relative to the other hub angularly offsetting the holes of one hub relative to the other hub from being concentric. The tufts extending from one of the radially innermost and outermost holes are stiffer than the tufts extending from the other one of the radially innermost and outermost holes imparting to the brush assembly tufts having different surface finishing and abrasive removal characteristics.

A method of delivering a glutinous substance to a workpiece from an end-effector comprises using the end-effector to rotate a brush relative to the workpiece about a rotational axis. The method also comprises, while rotating the brush relative to the workpiece about the rotational axis, urging the glutinous substance from the end-effector through a channel of a body of the brush from an axial inlet of the channel to an outlet of the channel, into contact with a thatch of bristles of the brush. Additionally, the method comprises using the end-effector to position the brush relative to the workpiece such that the glutinous substance in contact with the thatch is delivered onto at least a first surface and a third surface of the workpiece.

A brush (200) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (200) comprises a body (202), having a rotational axis (238) and comprising a first channel (208) that comprises an inlet (209) and a first outlet (280). The inlet (209) is coaxial with the rotational axis (238) and the first outlet (280) is offset from the rotational axis (238). The brush (200) also comprises tufts (222), extending from the body (202) and each comprising at least one bristle (220) and a tip (227). The brush (200) further comprises a first tube (210), communicatively coupled with the first outlet (280) of the first channel (208) of the body (202).

A brush for delivering a glutinous substance to a workpiece from an end-effector is disclosed. The brush comprises a body having a rotational axis. The body comprises a first end, a second end, opposite the first end, and a channel, comprising an axial inlet and an outlet. The axial inlet is at the first end of the body and is coaxial with the rotational axis. The brush also comprises bristles, extending from the body so that the bristles are not parallel to the rotational axis of the body.

A dental cleaning appliance includes a handle, and a cleaning tool detachably connected to the handle. The cleaning tool includes a nozzle for delivering a burst of working fluid to the teeth of a user, a stem extending between the handle and the nozzle, and a fluid reservoir for storing working fluid. The fluid reservoir is connected to, and extends around, the stem.
